[QUOTE="Jepalan, post: 8276820, member: 655519"] Make sure you connect a mono signal to both inputs of the amp. Put a Y-cable on one of your stereo outputs if you are in doubt. Autotek says the signal connected to the R & L inputs on their mono amps needs to be a MONO signal, not stereo. Then, as a starting point: Set head unit subwoofer level to 0db Set amp subsonic to 15Hz Set amp LPass to 80Hz Set amp boost to 0 Set amp bass eq to 0db Set amp Level to min (6v) Set head unit volume to 3/4 of max Play a 50Hz test tone Increase Level until amp clips and then back off a bit.
